Hi, I have had this problem for a week now. The oil boiler will run for a short while and then stop. If I check the pipes around the 3 way valve they are all hot and the pump is running but all the radiators are cold. I have a bleed valve next to the water tank and I bleed that frequently and there is always a small amount of air in that. I have bled all of the radiators and there is no air in them.
I can get the heating to come on if I drain water from one of the radiator drain valves and allow water to flow into the pressure vessel. After a few minutes the pipes around the 3 way valve become cold and the boiler will then kick in. It will then run fine for a number of hours.
After the boiler has been off for a few hours, like over night, the situation then repeats itself.
If I have an air lock and this is the problem I have run out of ideas on how to clear it or get the air to a radiator so I can bleed it out.
I would be very appreciative if someone could point me in the right direction please.
Thanks, Daniel.
